I was also in Stuttgart!
I travelled from Greece to Stuttgart and stay for 6 days. I Bought my ticket six months before.
I don't regret when my 14 - year old female, poodle travelled with me. Or when I left my 3 cats, at home alone (went a friend).
I think that, I would make it again. I hope the next time, I travel only to Athens.
Whitney! why didn't you come to Greece? You went everywhere apart from Athens.
